I think its both really. Frankly, I brought it, and am just glad I found a way to disable it (deleting "DLC014" files). I dont want a refund or anything, it would be silly for that cheap an item, but even for the sake of 'variety', there was no way to put up with this much ugly and this much wrong. I try to give everything a fair shake, but this specific pack is just a bad product. Its like.. someone woke up and decided to run a social experiment on customer loyalty.

Im sorry to the artists, this must be hard to read. This being said, can only improve given criticism;
Regarding skin tone, yes, too dark. Make it less Moorish. This being said, thats easy, the real suggestion relates to artistic design choices. Clearly the artist decided to value what seemed realistic over aesthetics but that recipe only goes so far. Compared to default faces, this pack made most Mediteranean faces ugly. Especially the women. I mean, this pack could be recycled as unique visuals for anyone with the Ugly trait. Aesthetics are important. They can be tempered with realism, but in a game about little armies, charts and data, the only eye candy we get are portraits. It should be taken into account.
